I am using xcode 3.26 with the latest tip on 10.68. I have to add JUCE_DISABLE_AU_FACTORY_ENTRY in order to compile AUs but even then there are some files added by the Introducer that don’t exist in the 10.6 SDK “AUPluginDispatch.*” After removing those manually, the audiounit builds but doesn’t validate:
Moving to Xcode4 requires upgrading to 10.7/10.8, to get the more recent versions and would break too much stuff right now to make it worthwhile for me. I’ve had a lot of trouble trying to compile RTAS stuff on Xcode4 with the latest compilers etc. Also i am much more productive on v3. Surely IntroJucer could be modified to make Xcode3 compatible AU projects quite easily? I understand your pain though
